Mars has been receiving a lot of attention recently. In the new Ridley Scott movie, The Martian, a NASA botanist is stranded on Mars and has to rely on his own ingenuity to survive. In real life, scientists have discovered evidence of present day water on the red planet.

On this edition of River to River, Ben Kieffer sits down with astrophysicists, Steve Kawaler of Iowa State University and Jasper Halekas of the University of Iowa, along with retired NASA astronaut, Clayton Anderson, to discuss the accuracy and impact of films like The Martian.
